> Choosing Monday for a surgery increases your chance of success 2 times

The title seems poorly worded. The researchers studied mortality rate, not success of procedures. Since these were elective surgeries, I assume the success rate was high. If your surgery has a baseline success rate of 90%, what would it mean to increase that 2 times?

The conclusion of the study was instead that the odds of death were 44% higher on Friday compared to Monday, and 82% higher on the weekend compared to Monday. Basically, there was a gradual increase in the odds of death from Monday to Thursday, but a big jump up on Friday and again on the weekend.
